According to Sky News, scientists have twice calculated the body mass index by more than 61,000 women, separated for 3 years and then continued for more than 11 years, during which more than 3,000 were infected with breast cancer.
Compared to women whose weight was stable during the first three years of study, those who lost at least 5 percent of their weight over the next three years were 12 percent less likely to die.

"Findings indicate that women can reduce the risk of cancer, even if they are overweight after weight loss," lead study author Ruan Chlebowski said.
